Use 'of_get_next_parent()' to simplify the while() loop and avoid the

v2: Use of_property_read_u32 instead of of_get_property+pointer dereference
*** Untested ***
Thanks.
Can someone with an mpc5xxx test this?
cheers
Hi,
I don't think it is an issue, but while looking at another similar
patch, I noticed that the proposed patch adds a call to be32_to_cpup()
(within of_property_read_u32).
Apparently, powerPC is a BE architecture, so this call should be a no-op.
Just wanted to point it out, in case of.
Best regards,
CJ
